Title:
PREPARATION METHOD FOR PANI/FE3O4/MWCNTS-PARAFFIN COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/157400
Kind Code:
A1
Abstract:
The present invention provides a preparation method for a PANI/Fe3O4/MWCNTs-paraffin composite material. The method comprises: putting a CNT and an acid liquid into a three-opening flask; putting the three-opening flask into an oil bath pan and performing mechanical stirring for hours, and performing suction filtration; and putting an obtained sample into a sample baking oven, so as to obtain an acidified MWCNTs suspension; adding a functionalized carbon nanotube into a beaker, and performing ultrasonic treatment to form a stable carbon nanotube suspension; adding 20 ml of 157 mg (0.4 mmol) (NH4)2FeSO4.6H2O and 386 mg (0.8 mmol) NH4Fe(SO4)2.12H2O to continue to perform ultrasonic treatment, so as to obtain an Fe3O4/MWCNTs heterogeneous structure; weighing and putting 0.02 g of Fe3O4/MWCNTs and 0.08 g of paraffin into a 100 ml beaker; adding 20 ml of ethyl ether; performing ultrasonic dispersion; after the ethyl ether is completely evaporated, cooling the mixture to a room temperature; putting the sample into a mold; pressing the sample into a cylinder. Compared with the prior art, the PANI/Fe3O4/MWCNTs-paraffin material prepared in the present invention has uniform surface coating, an orderly structure and very good dielectric properties.
